To all whom it may concern:

Be it known that I, CHARLES DELSEE, a citizen of the United States, anda resident of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in a SandpaperingHand-Plane, of which the following is a clear, full, and exactdescription. V

My invention relates to hand manipulated devices for sandapering andsmoothing floors and other p ain surfaces. Its object is to enable anoperator to utilize the action of a revolving cylinder having sand paperupon its circumference, wherebythe surface of the work when finishedwill not be wavy or irregular but perfectly smooth and plain, andwhereby the sand papering can be done quickly and with less fati ue, andcan. be adjusted to cut dee or sha ow, substantially as hereinafter fuy'described, and as particularly pointed'out in the claims.

In the drawings :Figure 1 1s a side elevation of my invention. Fig. 2.isa plan. view thereof. Fig. 3 is a longitudinal section of the same takenon dotted line 33, Fig. 2. Figs. 4 device.

the fulcrum connecting the yoke to the metal stock. Fig. 7 is alongitudinal central sec-- tion of the cylinder. Fig. 8 is a perspectiveview of said cylinder. Fig. 9 is a fragmental section taken on line 99Fig. 8,showing in detail the manner of lapping the engaging edges of theabrading surface of the cylinder. Fig. 10 is a plan view of a sheet ofabrading material showing the manner of cutting the same to fit thecylinder.

Referring to the drawings Arepresents the metal stock of my invention,which corresponds in shape to the metal stock of a carpenter'shand-plane, and has a handle B of suitable shape suitably secured to andarising from its rearend, and a hand-grasp a secured to and arising fromits'forward end, substantially as shown. The longitudinal edges of thisstock are, upward, and, at a suitab e transverse plane in front of thetransverse slot 0. thereof, these flanges b are developed into upwardlyprojecting fulcrumal lugs b. The bifurcated ends of a Urshaped yoke Care fulcrum'ed or pivotally connected by means of pins 0 to these. lugsb, and the parallel legs of this yoke C are, preferably, separateda-distance corresponding to that between the flanges of the stock, andextend back to atransverse and 5 are end views of the drum of the i Fig.6 is a vertical section throughreferably, flanged plane approximatelymidwa between the transverse slot a of the bloc and the rear endthereof, wherethey are connected by a tramsverse bar D, which latter, atits center of length, has a bifurcated arm 41 projecting rearwardlytherefrom. The branches of this bifurcated arm 11 extend to both sidesof the barrel of a nut E and enter'a circumferential groove e therein,and this nut has a milled wheel on its upper end for convenience v inmanipulating it, and engages a vertical screw-threaded post F secured toand arising from the center of width of the block, subs s'tantiall asshown in the drawings. The parallel egs of the yoke C are provided, inthe same transverse plane as the center of the slot a, with bearings f,f, for the journals of the cylinder G, which latter is of a widthslightly less than the length of the slot a, and is of such diameterthat when the yoke is properly adjusted vertically by means of the nutE, the cylinder can be lowered so that its lowest segment will assthrough the slot 0 andmove in a plane slow the slot of the stock;-'f0'rcan be raised out of and above the same; according as desired.

The circumferenceof the cylinderis'covered by a sheet of sand oremeryaper or other suitable cutting and abra ing material.

.When sand or emery-paper is used I prefer to cut the ends of the sameon the bias, and to provide an' oblique groove 9 in the circumference ofthe cylinder into which the edge of one of said bias ends is seated andsecured by extending the point or acute angle of the bias end of thefabric throu h the slot hat the end of said groove in t e overhangingedge of the cylinder, and la ping said pointed end of the sand paper bacunder the inner circumference of said overhanging edge and holding orsecuring it there by means of the pi iotal buttons, 3', j, substantiallyas shown.

en'one end of the sand paper is secured to-the cylinder in the mannerjust stated, said paper is drawn tightly around the. circumference ofthe cylinder so that its opposite biased end-overlaps the firstmentioned end and this overlappmg bias end is secured by extending thepomt or sharp angle thereof through aslot, k, in the overhanging ed e ofthe cylinder opposite that to which the uttons 7', j are pivoted, andinserting the extremity of said oint in the slotted end of a transverses in lo K. This spindle K exb. tends'throug suitable bearings in the webof the cylinder, and its end opposite that'to designed with t ,arevoluble abrading stock, a horizontally disposed yoke in which of thecylinder, and-the reverse motion of the spindle is prevented by theengagement of t e pawl o with the said ratchet m.

In operation the c linder is removed from its bearings in the yoke whenit is desired to cover the same with sandaper, and the bearin s in theleg s of the yo (e are is end in wow. When properly journaled in saidbearings one of its journals extends throu h its bearings and is adaptedto. form the s aft of the armature of a suitable electric motor (notshown) or may have a suitable pulley ,(not' shown) secured thereto,which may be connected by a suitable system of belting to an adequatesource of power. B adjusting the yoke up or-down by means 0 the nut thedepth of the cut or abrasion of the sand paper covered cylinder may beregulated as desired.

While the means for raising and lowering the cylinder are deemedsufficient, yet, if desired, the fulcrum of the ends of the yoke may beslightly raised or lowered by making the barrels of the pivotal insengaged by the bifurcated ends of the yo e offset, that is, reduced indiameter and with their center concentric to that ortion of the saidpins engaging the lugs 6 b All such changes in the details ofconstruction of my invention, including means for securing the sandpaper to the circumference of the cylinder, I desire to be considered{as contemplated within the $00 e of my -1nvention.

- that I claim as new is 1. A sand-papering hand-plane comprisingcylinder, a suitable said cylinder is journaled having one of its endsadjustably and pivotally secured to said stock, and means for adjustingthe opposite free kend of said yoke toward and from the stoc 2. Asandpapering hand-plane compris' a suitable stock having bearing mg lugsarising from the sides thereof, a yoke having the forward ends of itslegs adjustably and pivotally mounted in said lugs, a revoluble abrasivecylinder j ournaled in said yoke, a post engaging the rear end of saidyoke, and means on yoke, and a screw-threade said lugs for adjustablyjournaling the forward ends of the legs of the yoke.

3. A sand-papering hand-plane comprising a suitable stock having bearinglugs arising from the sides thereof, a yoke having the forward ends ofits le s adjustably and pivotally mounted in said ugs, a revolubleabrasive cylinder journaled in said yoke, a screwthreaded post having anadjusting nut thereon engaging the rear end of said yoke, and means onsaid lugs for adjustably ournaling the forward ends of the legs of saidyoke.

4. A sand-papering hand-plane comprising i a suitable stock havingbearing l'ugs arising from the sides thereof provided with elongatedslots, a yoke having the forward ends of its le s adjustably secured insaid slots, a revoluble abrasive cylinder journaled in said yoke, and aof said yoke.

5. A sand-papering hand-plane comprising a suitable stock having bearinglugs arising from the sides thereof provided with elonpost engaging therear end gated slots, a yoke having the forward ends of the legsadjustably secured in said slots, at revoluble abrasive cylinder'ournaled in said (i post having an adjusting nut thereon engaging therear end of said yoke.

6. A sand-papering hand-plane comprising a suitable stock having bearinglugs arising from. the sides thereof provided with elongated slots, ayoke having the forward ends of its legs adjustably secured in saidslots, a revoluble abrasive cylinder in said yoke, a post engaging therear end of said yoke, an adjusting cam engaging the forward end of thelegs of said yoke, and a nut on the journals of said legs for lockingthe same in their adjusted position.

7. A sand-papering hand-plane comprising a suitable stock having bearinglugs arising from the sides thereof provided with elongated slots, ayoke having the forward ends of its legs adjustably secured in saidslots, a revoluble abrasive cylinder in said yoke, a screw-threaded posthaving an adjusting nut thereon, an adjusting cam engaging the forwardend of the legs of the yoke, and a nut on the journals of said legs forlocking the same in their adjusted position.

In testimony whereof I have hereunto set my hand and seal this 12th dayof June, A. D.
